Combining multiple collections or sub collections, into a single search index

[dochonglo]

Hello!

I'm interested to know how to set up and combine multiple collections or sub collections into a single search index. For example, my sub collections in Firestore is in the following configuration: group/1234/activities.

Effectively, I have many groups with different IDs, where each has a sub collection of activities. I'd like for users to search the sub collection of all activities (similar to how a collection group query works).

However, I'm challenged with configuring the extension. At the moment, this is what I have:

I'd like to know if this is the right way to do this? Is my thinking and implementation correct? If not, what do I need to do differently to achieve my desired result? I've seen approaches where people have installed multiple extension instances, is that an approach that I should be using instead?

Thank you in advance for any help!! Also, would much appreciate it if there are any helpful resources anyone suggest regarding this case! :)

Hey @ismaelbarry

The Algolia Extension does not support multiple collection to one Algolia index at this time. I am currently looking for a way to support this use case but I have not found an elegant solution. I will update this ticket if I can come up with a solution that can address this gap.

also, can you provide me in detail what you are trying to do and the end result json. This way I know my solution will address your use case.

you can look at issue #103 but I am trying to see if I can implement a better approach.

@dochonglo and @smomin - I found the answer as you all may have. You install a firestore extension for each collection (point the collection path to each unique collection) then point the Index Name to the same index. That's it.
